1. Container (1) for submicron particles, which comprises:
- an internal space (2) for storing the submicron particles,a filling valve (3) for filing the submicron particles, having an open state allowing the submicron particles to pass through the filling valve between the internal space and the exterior of the container and a closed state preventing the submicron particles from entering or leaving the internal space through the filling valve, said filling valve being equipped with locking means (33, 34, 35, 36) arranged for locking the filling valve in its closed state and for preventing the opening thereof when this filling valve is not connected to a filling pipe (45),an emptying valve (4) for emptying the submicron particles, having an open state allowing the submicron particles to pass through the emptying valve between the internal space and the exterior of the container and a closed state preventing the submicron particles from entering or leaving the internal space through the emptying valve, said emptying valve being equipped with locking means (33, 34, 35, 36) arranged for locking the emptying valve in its closed state and for preventing the opening thereof when this emptying valve is not connected to an emptying pipe (46),a connector (12) arranged in order to be open to allow passage of fluid through this connector between the exterior of the container and the internal space when it is connected to a complementary connector of a source or discharge of fluid and to be closed to prevent passage of fluid through this connector between the internal space and the exterior of the container when it is not connected to the complementary connector of the source or discharge of fluid.

Abstract
A container with improved sealing, for improved security in the event of loading, transporting and/or unloading submicron particles, in particular nanopowder/nanoparticles, includes a connector for injecting liquid and/or gas. Such a container can also contain at least one inflatable seal (40) valve (3; 4). The container is provided with elements for changing the physical state of the material by heating, mixing or ultrasound bombardment. A method for using the container and an inflatable seal valve are also described.

27. Filling or emptying valve (3;
-
4), having an open state allowing objects to pass through it and a closed state preventing the objects from passing through it, said valve being equipped with locking means (33, 34, 35, 36) arranged for locking the valve in its closed state and for preventing opening thereof when this valve is not connected to a filling or emptying pipe (45;
46), further comprising a swivel plate (26), which;when the valve is closed, is in a horizontal state and seals the valve, when the valve is open, is in a swiveled state with respect to its horizontal state so that it no longer seals the valve, this valve further comprising; a seal (40) arranged to be in contact with at least one part of the perimeter of the swivel plate when the plate is in its horizontal state so as to ensure hermeticity of the valve when this valve is closed, and means (41, 42, 43) for inflating the seal against the swivel plate in its closed state.
-
4), having an open state allowing objects to pass through it and a closed state preventing the objects from passing through it, said valve being equipped with locking means (33, 34, 35, 36) arranged for locking the valve in its closed state and for preventing opening thereof when this valve is not connected to a filling or emptying pipe (45;
